Power flow control and loss minimization with unified power flow controller (UPFC)
Canadian Conference on Electrical and Computer Engineering 2004 (IEEE Cat. No.04CH37513), 2004In this paper, the UPFC injection model is used to investigate its effect on load flow and loss reduction in power systems. In this study, the Newton-Raphson algorithm is modified to consider the benefits of having a UPFC in the power system. Simulations have been implemented in MATLAB and the IEEE 14-bus system has been used as a case study ...

Genetic algorithms-based power flow control with unified power flow controller
3rd International Conference on Advances in Power System Control, Operation and Management (APSCOM 95), 1995This paper uses a genetic algorithm (GA) to solve optimal power flow control problems with a unified power flow controller (UPFC). UPFC is used as a continuous phase shifter to regulate both angle and magnitude of branch voltage. The GA, coupled with P-Q power flow, selects the best regulation to minimize the real power loss and keep the power flows in
